262 vs 267 sbc
 

Which of these is the more under factored and would be worth working with? The 3.50" bore sounds way to small but didn't one of those engines qualify well at Indy one year in an El Camino? Dime rockets or?

Call or PM Billy Nees. I think He has experience with both those. He is the expert. PM me and I will give you his number.

I think you are referring to an El Camino that had a 262 (4.3) V-6 that was near the top at Indy a few years ago. I think the last name was Fickler. Was the wife of a guy that worked at Aeromotive. Now the best 262 V-8 I know of, is a guy out of Div 1- Brian Philbrick(sp?) out of Ontario, Canada. I have been working on the 267 combination for a little while and have found good things and some bad things about the 267. Some can be cured with money and others, well you just have to live with. The big issue with either combination is going to be finding good cores to work with, especially the 262 V-8. I have collected a bunch of 267 stuff and more carbs than should be allowed in one shop.

This is interesting because I saw Briane's (car at the Class Nationals.
We had a short conversation about the small engines.
Great guy.

Curious these two engines so close in cubic inches.
Kind of wonder why GM made them in the first place?
Then they the different displacements?

Wondering which of these two engines GM used to manufacture the mini LT1?
OR was it a whole new bore stock combination?

Probably an emissions experiment.

Re: 262 vs 267 sbc
 

Mini lt1 different again, went back to 265 same dimensions as the fifties engine.

Re: 262 vs 267 sbc
 

interesting original 265 is 3.75bore X 3 stroke- small dimension rod bearings
262 is 3.67 bore X 3.1 stroke-large dimension rod bearings
267 is 3.5 bore X 3.48 stroke-also large dimension rod bearings

262 was a popular engine in the Monza it replaced a 350 that was substituted at introduction in 1975 due to engine shortages -only available for 2-3 years

I believe that El Camino was Bob Shaw's old car. And I think it was a 229 ci.

Re: 262 vs 267 sbc
 

You may be right. I do remember he had one, but can't remember much more than that. Debra Fickler was the lady I remembered in a 4.3 V-6-262 EFI El Camino. Seems like the Fickler El Camino was usually a good qualifier. 262 V-8 was 75-76 only and 267 V-8 was 79-82. The 267 is auto only, although I saw one with a 4 speed in a Malibu at GM. If Dad was still living, he could tell me why they had that car, built that way.

Re: 262 vs 267 sbc
 

Shaw's elCamino was 4.3 v6 (262 cid) with TBI fuel injection.

It's a 350 v8 with two cylinders removed.

Everything equal and same displacement, more cylinders will make power than smaller number of cylinders up a v10/v12.

More small intake strokes per four stroke cycle makes more power than fewer and larger intake strokes. The carb acts larger than it actually is with more cylinders.
